THE ESTIMATES OF COST.


tiOn Of Them.
City Engineer Eaton has made ou
and will submit to the Council mex
Monday the following report OF
sewers: la
To the Hon. the President and Counci
Of Los Angeles:
GENTLEMEN: i herewith transmit tt
your honorable body the report of Mr.
Rudolph Herring, consulting engineer
together with the data required by The
statute for embodying in the ordinance
declaring the necessity for sewer.
age, etc.
Mr.. Herring, in addition to reporting
the plan, has given valuable knowl,
edge that will simplify and aid ma
terially in making up the details
Most Of the branch sewers have been
laid down on the design plan, and the
general flushing arrangements settled
upon. The profiles OF all the streets
in the city with the exception of per.
haps dozen have been taken; so the
work of completing the design in de-
tail will progress from now on without
interruption.
1t is quite probable the location oi
some Of the sewers will be slightly
modified when constructed, as they
pass through private property in a
number Of places. This is not desir-
able when possible to avoid, and
steps should be taken to have streets
laid out along or near the sewer lines
that pass through property not yet sub
divided.
In describing the location OF
-outfall sewer, sufficient latitude
has been reserved for modifica-
ton of the present alignment
should the necessity arise from diff
Guilty in securing a right of way.
The estimated cost submitted herein
is based upon the present prices of
labor and materials; and it is not
likely that material reduction will
take place before the bulk OF the con-
tracts are let. The estimate with
pressed brick on the inside of the in
vert has been reduced about $50 900
by substituting an extra made COM
mon brick. 1t was not so much to Sc
cure the smoother surface that the
pressed brick was recommended as to
get one that would stand the erosive
action under which our common brick
would in time give way.
The latter estimates footed up in ex-
cess about l per cent. of the round
million and it has been prorated
among all the sewers, go that their
total will give that even figure. Z
No provision was made in the esti-
mate for purchases of right of way,
nor for the engineering and inspection.
These expenses, however, will be
amply covered by the direct assess
ments from the abutting frontage
along the sewer lines.
AS the season for making brick is
getting well advanced, l would sug-
gest that bids be asked at once for
supplying one million extra quality
hard brick and one million hard burnt
and merchantable. The points at
which the brick shall be burnt should
be designated as along the Santa
Monica and Ballona railroads.
These two roads will place nine
tenths of all the brick sewer material
within haul of one mile.
The following is summary of ap-
proximate quantities in the estimate ::
4,93l 900 extra common invert
brick.
f12,S33,0 900 common hard burnt
brick.

The form of all sewers mentioned
herein below, is to be what is known
as the new form egg shape, when not
otherwise specified, and all dimensions
indicating sizes, refer to the interior of

oUTFALL SEWER.
Commences at point on the beach
of the Pacific Ocean in Sec. 10 of T
2 s, R Is w, and runs in practically
direct northeast course to the inter-
section Of east boundary of Agricul-
tural Park property and the south
charter boundary of the city; thence
following the south charter boundary
to q point where Grand avenue would
intersect the same, if produced. The
sewer is further described as passing
over and through sections 10, IL, 3
